This question is not directly related to SuSE but since I'm using SuSE 8.2 I'm hoping there are users on this list who are knowledgeable about hardware. The table below shows my present and proposed drive setup. IDE Mast/Slave Present Proposed 1 Master 80G HD 80G HD 1 Slave 40G HD CDROM 2 Master CDROM 40G HD 2 Slave ZIP Drive Zip Drive 3 Master CDRW CDRW My present setup has the two Hard Drives on the First IDE as Master/Slave. I currently use SuSE on the 80G HD and use the 40G HD as storage. I'm installing a second version of SuSE onto the 40G HD and will use both versions from time to time. Does it make any difference in performance if the HD is Master or Slave. Would I get better performance from the 40G HD if it were mounted as Master on the Second IDE? Thanks, Terry
